Answer:

f(5.9)= 15.7

Step-by-step explanation:

f(x) = 3x -2

f(5.9) = 3(5.9) -2

f(5.9) = 17.7 -2

f(5.9) = 15.7

Word Explination

If the (x) in f(x) is replaced by another variable (in this case, a number) any other x seen in the equation is replaced by that variable. For this question, the x in f(x) is replaced by 5.9. And so any other x in this equation needs to be replaced by 5.9 as well. From there on out, you solve.

Answer:

4.00

Step-by-step explanation:

Given

x:   2  ,      5   ,     8     , 12

y: 8.50, 15.25, 22.00. 31.00

Required

Determine the y intercept

First, we calculate the slope:

\(m = \frac{y_2- y_1}{x_2 - x_1}\)

Where

\((x_1,y_1) = (2,8,50)\)

\((x_2,y_2) = (12,31.00)\)

\(m = \frac{31.00 - 8.50}{12 - 2}\)

\(m = \frac{22.5}{10}\)

\(m = 2.25\)

Next, we calculate the equation:

\(y - y_1 = m(x - x_1)\)

Where:

\((x_1,y_1) = (2,8,50)\)      

\(m = 2.25\)

The equation becomes:

\(y - 8.50 = 2.25(x - 2)\)

\(y - 8.50 = 2.25x -4.5\)

Make y the subject

\(y = 2.25x -4.5+8.50\)

\(y = 2.25x +4\)

Take \(x =0\); to get the y intercept

\(y = 2.25*0 +4\)

\(y = 4\)

Hence, the y intercept is 4.00

There would be 11 cylindrical buckets required to fill the empty aquarium with 65 gallons.

A cylinder is three dimension solid, which has two circular base and which are connected by a curved surface.  

Given that,

The diameter of cylindrical bucket d is 12 inches

so radius r=6 inches

And the height of bucket is 11.25 inches.

Volume of cylinder=π×r^2×h

Let n buckets are required to fill 65 gallons.

Since, 1 gallon = 231 inches,

65×231=n×22/7×6×6×11.25

To find the double integral of f(x, y) = 3/2x + y² over the region R bounded by the circular arc x² + y² = 1 above the x-axis, we can use a coordinate transformation to convert the integral into polar coordinates.

In polar coordinates, the circular arc x² + y² = 1 corresponds to the equation r = 1, where r is the distance from the origin to a point on the curve. The region R can be represented in polar coordinates as 0 ≤ θ ≤ π, where θ is the angle measured from the positive x-axis to the point on the curve.

To perform the coordinate transformation, we substitute x = rcosθ and y = rsinθ into the integrand f(x, y):

f(x, y) = 3/2x + y²

= 3/2(rcosθ) + (rsinθ)²

= 3/2rcosθ + r²sin²θ.

The Jacobian determinant for the coordinate transformation from (x, y) to (r, θ) is r, so the double integral becomes:

∬R f(x, y) dA = ∫₀ᴨ ∫₀¹ (3/2rcosθ + r²sin²θ) r dr dθ.

Now, we can evaluate the double integral by integrating first with respect to r from 0 to 1, and then with respect to θ from 0 to π. This will give us the value of the integral over the region R bounded by the circular arc x² + y² = 1 above the x-axis.

The equation equivalent to the simple interest formula A = P(1 + rt), that Celo used is P = A/(1 + rt). Hence, the first option is the right choice.

Equivalent equations are the equations that are transformed from one equation to another equation, but the final values they give are equal. It's just the change of the variable on which the equation is derived.

The simple interest equation that Celo used is A = P(1 + rt).

This is currently used to find the final amount A.

On isolating P to one side of the equation in the following ways:

A = P(1 + rt),

or, A/(1 + rt) = {P(1 + rt)}/(1 + rt) {Dividing both sides by (1 + rt)}.

or, A/(1 + rt) = P {Simplifying}.

The conditional probability that, when flipping a non-biased coin four times, there are at least two heads, given that the first flip is a head, is 3/4.

Calculating the Conditional Probability:

Let us assume that getting a head in the first flip of coin is event B

Also, let us assume that getting a head in on of the remaining three flips is A

Then we have to find the probability of A given B, that is, P(A|B).

The formula for conditional probability is given as follows,

P(A|B) = P (A∩B) / P(B)

The probability of getting two heads, P(A∩B) = 3/8

The probability of getting head in the first flip, P(B) = 1/2

∴ P(A|B) = (3/8) / (1/2)

P(A|B) = 3/4

Thus,  the conditional probability of getting at least two heads, given that the first flip is a head is 3/4.

Answer:

67.5$

Step-by-step explanation:

75$ x .10 = 7.5$

75$ - 7.5$ = 67.5$

Answer:

$67.50

Step-by-step explanation:

First, find the discount.

Multiply the discount rate by the cost.

discount rate * cost

The discount rate is 10% and the cost is $75.

$75 * 10%

Convert 10% to a decimal. Divide 10 by 100 or move the decimal place two spots to the left.

10/100 = 0.10       or         10.0 --> 1.0 --> 0.10

$75 * 0.10

$7.5

Now, find the final price.

Since it is a 10% discount, we must subtract the discount amount from the cost.

cost - discount

The cost is $75 and the discount is $7.5

$75 - $7.5

$67.50

The final price of a item that costs $75 with a 10% discount is $67.50

Step-by-step explanation:

Angles and Lines

The figure shows a kite ABCD where the following data is given:

\(m\BAE=28^\circ\)

\(m\BCE=58^\circ\)

We also know

\(BC\cong CD\)

\(AB\cong AD\)

Since triangle BCD is isosceles, it follows that:

\(m\angle CBE=m\angle CDE\)

And triangles BCD and DCE are congruent.

Thus:

\(m\angle BCE=m\angle DCE=58^\circ\)

And also:

\(m\angle BCE=58^\circ+58^\circ=116^\circ\)

Since the sum of internal angles of BCD is 180°

\(m\angle CDE=m\angle CBE= ( 180 - 116 ) / 2=32^\circ\)

The sum of angles of triangle CDE is 180°, thus

\(m\angle CED=180^\circ - 32^\circ - 58^\circ = 90^\circ\)

Angles CED and BEA are vertical (opposite), thus:

\(m\angle BCE=m\angle CED= 90^\circ\)

Finally, since the sum of the angles of triangle ABE is 180°

\(m\angle ABE= 180 - 90 - m\angle BAE\)

\(m\angle ABE= 180^\circ - 90^\circ - 28^\circ = 52^\circ\)

\(\mathbf{m\angle ABE=52^\circ}\)

To show that the matrix A = [XX - X'Z(ZZ)^(-1)Z'X] is positive definite, we need to demonstrate two properties: (1) A is symmetric, and (2) all eigenvalues of A are positive.

Symmetry: To show that A is symmetric, we need to prove that A' = A, where A' represents the transpose of A. Taking the transpose of A: A' = [XX - X'Z(ZZ)^(-1)Z'X]'. Using the properties of matrix transpose, we have:

A' = (XX)' - [X'Z(ZZ)^(-1)Z'X]'. The transpose of a sum of matrices is equal to the sum of their transposes, and the transpose of a product of matrices is equal to the product of their transposes in reverse order. Applying these properties, we get: A' = X'X - (X'Z(ZZ)^(-1)Z'X)'.  The transpose of a transpose is equal to the original matrix, so: A' = X'X - X'Z(ZZ)^(-1)Z'X. Comparing this with the original matrix A, we can see that A' = A, which confirms that A is symmetric.  Positive eigenvalues: To show that all eigenvalues of A are positive, we need to demonstrate that for any non-zero vector v, v'Av > 0, where v' represents the transpose of v. Considering the expression v'Av: v'Av = v'[XX - X'Z(ZZ)^(-1)Z'X]v

Expanding the expression using matrix multiplication : v'Av = v'X'Xv - v'X'Z(ZZ)^(-1)Z'Xv. Since X and Z have full column rank, X'X and ZZ' are positive definite matrices. Additionally, (ZZ)^(-1) is also positive definite. Thus, we can conclude that the second term in the expression, v'X'Z(ZZ)^(-1)Z'Xv, is positive definite.Therefore, v'Av = v'X'Xv - v'X'Z(ZZ)^(-1)Z'Xv > 0 for any non-zero vector v. Implications in econometrics: In econometrics, positive definiteness of a matrix has important implications. In particular, the positive definiteness of the matrix [XX - X'Z(ZZ)^(-1)Z'X] guarantees that it is invertible and plays a crucial role in statistical inference.

When conducting econometric analysis, this positive definiteness implies that the estimator associated with X and Z is consistent, efficient, and unbiased. It ensures that the estimated coefficients and their standard errors are well-defined and meaningful in econometric models. Furthermore, positive definiteness of the matrix helps in verifying the assumptions of econometric models, such as the assumption of non-multicollinearity among the regressors. It also ensures that the estimators are stable and robust to perturbations in the data. Overall, the positive definiteness of the matrix [XX - X'Z(ZZ)^(-1)Z'X] provides theoretical and practical foundations for reliable and valid statistical inference in econometrics.

The smallest number of eggs that could have been in the box is 1134

The problem is to find the smallest number of eggs that could have been in the box, given the remainder when taking them out by different numbers. Here are the moves toward tackling it:

Allow n to be the quantity of eggs in the container. Then we have the accompanying arrangement of congruences:

n ≡ 1 (mod 2)

n ≡ 1 (mod 3)

n ≡ 1 (mod 4)

n ≡ 1 (mod 5)

n ≡ 1 (mod 6)

n ≡ 0 (mod 7)

For this problem, we have k = 6 k = 6, a i = {1,1,1,1,1,0} a_i = {1,1,1,1,1,0}, M i = {1260,840,630,504,420,720} M_i = {1260,840,630,504,420,720}, and y i = {−1,−2,−3,-4,-5,-6} y_i = {-1,-2,-3,-4,-5,-6}.

Plugging these values into the formula and simplifying modulo 5040, we get:

n = (−1260 + −1680 + −1890 + −2016 + −2100 + 0) mod 5040

n = (−8946) mod 5040

n = (−3906) mod 5040

n = 1134 mod 5040
